If you want to compile an image, bootable or not, you propably have assembled your disc-files in a folder.Discalot is assisting you to create an image of this directory structure.Choose a custom boot sector or two (UEFI), to extend boot options.Various options for file system (UDF, Joliet, ISO 9660) are provided.Use the whole spectrum of oscdimg command line options in a graphical user interface.

I am glad you make your tool public, I assume this is a new build and renamed Discom, Is that right?

If my assumtion is right, let me suggest you to let the other members of the forum and occasional visitors know this tool may also use grldr (from grb4dos) as boot sector in order to make a Multiboot DVD with several ISO's on it called from menu.lst

Non writable media is always the safest way to deal with potentially infected PC's

Also not all people who visit this forum is an advanced user, so I think it would be good to explain a little more how to use it, just as you explained me on PM (very clearly by the way).

A little promotion is always good, particularly for a good and usefull tool like this.

Indeed, I had to rename it to Discalot because the other name is owned by a company.
Checked it too late.

Yes, you are right, you can use Discalot/oscdimg to create grub-discs by selecting grldr as bootloader.

Thank you for this good advice.
I will try to extend the help-file for Discalot.

A little promotion is always good, particularly for a good and usefull tool like this.

I really appreciate this, and hope the tool will make it easy to create usefull discs.

-Install Discalot by the /s switch or [File]-[Extend Context Menu].-Set oscdimg.exe by -> Program -[Select].You can skip this if you have a copy of "oscdimg.exe" in the Discalot-folder.

Preparation: Mount a Windows7-Disc-ISO to drive or put a Windows7-Disc to your DVD-device. (also Win8 or Win10-discs will do)

Now you are ready to create your ISO.

-Select context menu "Make my Disc" by right-click on this drive.-When "Select bootloader" dialogue-window appeares - select etfsboot.com from inside the \boot folder.The provided etfsboot.com is the default bootloader for Win7-8-10 discs.-Then you are asked where to store the ISO-file you want to create.By default names are suggested for label and file-name.Finally the User-Interface shows all parameters to build the ISO.-In the [Compile]-Tab press [Create Image] to start the building process.

The procedure is similar if you choose a folder as source.

--------------------------------------------------------------Parameters by bootloader:By selecting "etfsboot.com" the script knows what parameters are to be set for NT6 discs.Selecting "bootsect.bin" lets the script know that you want to build a NT5 disc.Also the script knows what settings "grldr"-discs require if you choose it as bootloader.

-Users without administrative rights can extend the shell within their profile.
-default shell extensions for directory and drive are moved to "HKEY_CURRENT_USER\Software\Classes\..." to provide different settings for users.
-Admins can extend the shell for all users by /au switch at command line.
-on PE-systems "HKEY_LOCAL_MACHINE\Software\Classes\..." is used.
-different oscdimg files can be used for different OS-Architectures by locating files in %OSARCH%-folder (X86 / X64).
-changed default behavior to "trackless-mode", Config- and Log-File are only saved "on demand".
-added "Elevated Rights Detector"

Basically, that provision by IMGBURN is correct (and actually needed) if you use Isolinux versions earlier than 2.12, from 2.12 onwards it is not needed anymore as the boot-info-table is already correct in the isolinux.

We are talking of BIOS here, no idea about UEFI booting of Isolinux, there is a thread on Syslinux mailing list, including a "workaround" by ady for using oscdimg for images larger than 32 MB, but possibly in the meantime things have changed :
